Servo Motor Control System Block Diagram
In this the reference input at which the motor shaft has to maintain at a certain position is given to the rotor of synchro generator as mechanical input theta.
Servo motor control system block diagram. Field controlled dc servo motor. After reading this topic armature controlled dc servomotor in the control system you will understand the theory derivation expressions transfer function and block diagram. Block diagram of a position servo. Note the greek letter sigma meaning summation aka the controller surrounded by a circle.
Briefly a typical motor drive system is expected to have some of the systems block diagram indicated in figure 27 1. The back emf is proportional to the speed of the motor and hence. This is the summation or sum point where the input signal and the. This will give accurate and stable control over speed and position.
Usually the inductance of the armature winding is small and hence neglected. Below is a block diagram of a modern automated systems incorporate closed loop feedback for motion control. Below is the illustration of the various system level. The block diagram representation of the armature controlled dc servo motor is developed in steps.
Simple servo system block diagram figure 2 3 view a is a block diagram of a closed loop position servo. The load may be a conveyor system a traction system the rolls of a mill drive the cutting tool of a numerically controlled machine tool the compressor of an air conditioner a ship propulsion system a control valve for a. The field servo motor. The schematic diagram of servo system for ac two phase induction motor is shown in the figure below.
